Description
AC surge protection WPX-MPA30-275/3+N power module surge protector is consisting of three MOV type power supply module and one GDT, used for L-N, N-PE class two protection.
It is applied to equipotential bonding of the low voltage side of transformer or main low voltage distribution boxes inside the building, providing protection against the overvoltage arising from the lightning strike to power supply system of class I or faulty operation, but they are not applied to the system of the expected short-circuit current beyond rated breaking after flow current.
The series fuse must be at the front-end of the product, otherwise, the surge protector may be burned out by the developed power flow current, while the product is discharging.(option from standard IEC61643-1 and GB50343)
